heart-shaped bottom plate 12, a printed circuit board (PCB) 14, two
speakers 15, an inverter tube 16, a protective net 18, a battery
13, and a cover 11. The upper casing 17 defines a heart-shaped
opening 17a. The bottom plate 12 hermetically seals the opening 17a
to form a heart-shaped resonant chamber (not labeled) between the
upper casing 17 and the bottom plate 12. The PCB 14, the speakers
15, and the inverter tube 16 are received in the resonant chamber.
The PCB 14 is disposed on the bottom plate 12. The speakers 15 and
the inverter tube 16 are disposed on the PCB 14. The upper casing
17 defines two first through holes 176 and a second through hole
177. The speakers 15 protrude from the upper casing 17 through the
corresponding first through holes 176 and hermetically seal the
corresponding first through holes 176. The inverter tube 16
protrudes from the upper casing 17 through the second through hole
177 and hermetically seal the second through hole 177.
The PCB 14 may further include a power connector 140, a data
connector 141, and a power switch 142, disposed on one end of the
PCB 14. The upper casing 17 defines three third through holes 178
corresponding to the power connector 140, the data connector 141,
and the power switch 142, and includes a volume controller 172
mounted thereon and connected to the PCB 14. The power connector
140 protrudes from the upper casing 17 through one third through
hole 178 and seals the third through hole 178 to allow the sound
box 100 connecting to an external power source (not shown). The
data connector 141 protrudes from the upper casing 17 through one
third through hole 178 and seals the third through hole 178 to
allow the sound box 100 to be connected to an audio source (not
shown). The power switch 142 protrudes from the upper casing 17
through one third through hole 178 and seals the third through hole
178 to allow booting operation of the sound box 100. The volume
controller 172 is disposed on the upper casing 17 to allow manual
volume control of the sound box 100. However, the configuration of
the power connector 140, the data connector 141, the power switch
142, and the volume controller 172 is not limited to this
embodiment.
It is noteworthy that the configuration of the upper casing 17 and
the bottom plate 12 is not limited to this embodiment. In other
alternative embodiments, the upper casing, the bottom plate, and
the opening can be designed in other shapes. Also, the numbers of
the speakers 15 and the first through holes 176 are not limited to
this embodiment, but should be set depending on requirements.
In particular, the bottom plate 12 includes three positioning
columns 122 extending toward the upper casing 17. Each positioning
column 122 defines a first through threaded hole 123. The upper
casing 17 defines three fastener-receiving columns 173 extending
toward and aligned with the corresponding positioning columns 122.
The upper casing 17 and the bottom plate 12 are connected by
inserting three fasteners (not shown) through the corresponding
first through threaded holes 123 and into the corresponding
fastener-receiving columns 173. Also, the upper casing 17 and the
bottom plate 12 can be combined by other methods, such as,
structural engagement or adhesive.
The bottom plate 12 further includes a supporter 143 disposed
between the two speakers 15. The upper casing 17 includes a rib
174. The rib 174 is a plate extending toward the bottom plate 12
and positioned between the first through holes 176 and the first
hole 177. The rib 174 defines a cutout 175. The inverter tube 16 is
supported by the supporter 143 and extends through the cutout 175
to the second through hole 177. Thus, the inverter tube 16 is
secured within the resonant chamber by the supporter 143 and the
rib 174. Of course, the inverter tube 16 can be fixed in the
resonant chamber by other methods in alternative embodiments.
The protective net 18 is pasted on the upper casing 17, covering
the first through hole 176 and the second through hole 178 for
allowing sound to exit but blocking the entry of dust. To avoid the
protective net 18 adversely affecting the appearance and
interfering with the handling of the sound box 100, the upper
casing 17 defines a sunken surface 17b. The protective net 18
fittingly fills the sunken surface 17b.
The bottom plate 12 defines a groove 121 in a surface 12a facing
away from the upper casing 17. The battery 13 is fittingly received
in the groove 121. The cover 11 covers the surface 12a to secure
the battery to 13 to the bottom plate 12. In particular, the bottom
plate 12 also includes an electrical contact 124 that is disposed
in the groove 121 and electrically connected to the PCB 14. The
battery 13 is electrically connected to the PCB 14 by the
electrical contact 124 and supplies power for the PCB 14. The
battery 13 can be a rechargeable battery and recharged by the
external power source by the power connector 141.
The bottom plate 12 defines two engagement-receiving portions 125
at one side of the groove 121 and a blind threaded hole 126 at an
opposite side of the groove 121. The cover 11 is a flat board and
includes a front surface 110 and a back surface 111 opposite to the
front surface 110. The back cover 11 includes two engagement
portions 112 disposed on the front surface 110 corresponding to the
engagement-receiving portions 125. The back cover 11 also defines a
second threaded through hole 113 through the front surface 110 and
the rear surface 111. The cover 11 is secured to the bottom plate
12 by engaging the two engagement portions 112 with the
engagement-receiving portions 125 and inserting a fastener (not
shown) through the second through threaded hole 113 and into the
blind threaded hole 12. Of course, the cover 11 can be secured to
the bottom plate 12 by other methods.
The cover 11 includes two first connecting plates 21 extending
upwards from the back surface 111, adjacent to an end of the cover
11. Each first connecting plate 21 defines a first connecting hole
210. The two first connecting holes 21 are aligned with each other.
The clip 20 includes a clipping plate 24, a shaft 23, and a coil
spring 22. The clipping plate 24 includes two second connecting
plates 240 extending upward from a surface of the clipping plate
24, adjacent to an end of the clipping plate 24. Each second
connecting plate 240 defines a second connecting hole 241. The
second connecting holes 241 are aligned with each other. The
distance between the second connecting plates 240 is slightly
farther than between the first connecting plates 21. The shaft 23
extends through one second connecting hole 240, one first
connecting hole 210, the coil spring 22, the other first connecting
hole 210, and the other second connecting hole 240 in sequence.
Thus, the clipping plate 24 is connected to the cover 11. The coil
spring 22 is configured for applying a torsional force to the
clipping plate 24 so that an end of the clipping plate 24 opposite
to the second connecting plate 240 abuts the cover 11. In this
embodiment, the clipping plate 24 further includes two gripping
teeth 241 formed at the end of the clipping plate 12 opposite to
the second connecting plates 240 to increase a gripping force of
the clip 20.
It will be understood that the above particular embodiments and
methods are shown and described by way of illustration only. The
principles and the features of the present disclosure may be
employed in various and numerous embodiment thereof without
departing from the scope of the disclosure as claimed. The
above-described embodiments illustrate the scope of the disclosure
but do not restrict the scope of the disclosure.
